FYI: We try to leave jargon out of our videos, but if you want to learn more about this topic, here are some handy keywords to get your googling started:
Crypsis: An animal’s ability to avoid detection by other animals. Tigers use camouflage crypsis as part of their predation strategy.
Apex Predator: An animal on top of the food chain with no natural predator in its ecosystem.
Camera Trap: A motion-sensor activated camera to capture images of animals in the wild with as little human interference as possible.
Cultural Climate: Shared perceptions and attitudes in a particular area.
